The importance of this previously unpublished Tantra consists in the fact that it belongs to what some call the “prohibitive” class, alleging it to belong to, and have been operative in, another and not in the present Age (kalpa). The Tantra is of interest particularly as it deals with the vexed subject of the existence or non-existence of Pashu-bhava in the Kaliyuga and the ritual use of the panchatattva. REVIEWS “The field of ancient Indian literature has been enriched by this praise-worthy edition of an important Tantric text, and both the interested public and the Agamanusandhana Samiti can be congratulated for this finely got-up book……Glory of the spiritual Sadhana of India”. --- Dr. Sunìti Kumar Chaterji in The Calcutta Review. “The author has indirectly shown that taking its philosophical aspect into consideration, it can attain a very high level and compare favourably with, or even excel, the doctrines of Sànkhya or Màyàvàda”. --- Quarterly Journal of the Mythic Society.
